Description
2-(Dimethylamino)ethyl methacrylate, commonly abbreviated as DMAEMA or DM methacrylate, is a tertiary amine-functional monomer with CAS number 2867-47-2. It carries no E-code designation and is not classified as a food additive. It is commercially available under several trade names depending on the supplier.
In polymer chemistry, DMAEMA serves as a reactive monomer in the synthesis of cationic and pH-responsive polymers used in textile finishing agents, pressure-sensitive adhesives, and water-based coatings. Its dimethylamino group enables quaternisation and protonation reactions, allowing formulators to tune charge density and crosslink density within the polymer network.
DMAEMA is supplied as an inhibited-grade liquid for handling stability during storage and transport. It falls under REACH regulation and requires an up-to-date Safety Data Sheet for EU procurement. Packaging is typically available in drums and IBC containers, with technical-grade specifications standard across the supply chain.
